How to Calculate PTR & PTS in Indian Pharma — Formula & Example

Under the Drug (Prices Control) Order (DPCO) enforced by the National Pharmaceutical Pricing Authority (NPPA), trade margins are applied on the price exclusive of GST. MRP printed on the pack is GST-inclusive, so the GST component must be backed out before margins are applied.

PTR Formula

PTR = (MRP × (100 − Retailer Margin%)) ÷ (100 + GST%)

Example — MRP ₹100, 20% margin, 12% GST:
PTR = (100 × 80) ÷ 112 = ₹71.43

PTS Formula

PTS = PTR × (100 − Stockist Margin%) ÷ 100

Example — PTR ₹71.43, 10% stockist margin:
PTS = 71.43 × 0.90 = ₹64.29

Worked Example: Antibiotic Strip — MRP ₹150, 12% GST

Parameter Calculation Amount (₹) Notes
MRP (incl. 12% GST) Printed on pack ₹150.00 Maximum patient selling price
Base price (excl. GST) 150 ÷ 1.12 ₹133.93 Trade base before tax
Retailer margin (20%) 133.93 × 20% ₹26.79 Chemist's DPCO-mandated profit
PTR (to retailer) 133.93 − 26.79 ₹107.14 Billed by stockist to chemist
GST on PTR (12%) 107.14 × 12% ₹12.86 Chemist claims as ITC input
PTS (to stockist, 10%) 107.14 × 90% ₹96.43 Manufacturer invoice to stockist

Frequently Asked Questions

PTR (Price to Retailer) is the net price at which a retail medical store buys from a wholesale stockist. PTS (Price to Stockist) is the price at which the stockist buys from the manufacturer's C&F agent. MRP → PTR → PTS represents the full backward price chain.

MRP is GST-inclusive. Under NPPA/DPCO, trade margins are calculated on the ex-GST price. The GST component the chemist pays on PTR is later claimed back as Input Tax Credit (ITC) when filing GSTR-3B.

For a 10+1 scheme the chemist pays for 10 strips but receives 11:
Effective PTR per unit = (Billed PTR × 10) ÷ 11

MymBill auto-calculates effective landed costs and batch-level margins on every scheme purchase.

All medicines listed in Schedule I of the DPCO 2013 (National List of Essential Medicines) have ceiling prices set by NPPA. Non-scheduled formulations can have market-driven MRPs, but trade margins are still customarily 20% (retailer) / 10% (stockist).
